Testing fuel pressure part 2 (97 lesabre

http://www.automotiveforums.com/vbul....php?t=1051068
OK GUYS,need some help if you read (part 1)fuel pump
lasted 2 days until long cranking time was back??
when i rechecked fuel pressure ZER0.hmmmm WHAT
happened.now you have to prime it 3 or 5 times or a shot
of ether to get it going.pressure only reads 20psi w/fpr vacuum
on or off & drops right off when engine is turned off.so i blocked off return line no difference key on 0, run 20, & wont hold pressure
when shut off.my question, is the FPR still in the loop when i
block return at fuel rail. i think it has to be because its before
the return line.if it is then i can see a bad regulator but if not
it puts me back to pump/lines to see what i did wrong
Thanks again mike
